The AI-first alternative to Synthflow
Synthflow gets a non-technical team to a live AI voice agent fast. Orbit gets you there too — and the messaging, email, video, and contact center around that agent ship on the same account.
Orbit vs Synthflow, in one answer
Orbit is the AI-first alternative to Synthflow that goes past the phone call: launch an AI voice agent just as quickly with pre-built templates, then reach the same customers over SMS, WhatsApp, RCS, email, video, and a built-in contact center on one platform and one pay-as-you-go bill — with the quality scoring, post-call synthesis, and memory a voice-only tool leaves to you.

Orbit vs Synthflow — frequently asked
- Is Orbit a good Synthflow alternative?
- Orbit is the AI-first alternative to Synthflow. Synthflow is a voice-only, no-code builder; Orbit pairs AI voice agents with SMS, WhatsApp, RCS, email, video, and a contact center on one platform. You get AI voice agents plus every other channel on one platform and one pay-as-you-go bill, with self-serve signup and no annual contract minimum.
- What does Orbit offer that Synthflow doesn't?
- Synthflow is a voice-only, no-code builder; Orbit pairs AI voice agents with SMS, WhatsApp, RCS, email, video, and a contact center on one platform. Orbit runs AI voice agents, SMS and MMS, WhatsApp, email, embeddable video, and a built-in contact center on a single platform with one unified bill, instead of separate products you integrate and reconcile yourself.
- How does Orbit's pricing compare to Synthflow?
- Orbit is pay-as-you-go with pricing published on the website, self-serve signup, and no annual contract minimum. Every channel is billed on one account, so you get a single invoice across voice, messaging, email, and video instead of a separate bill per product — and the rate you see is the whole cost: no per-product fees, no carrier or compliance surcharges, and no paid support tier stacked on top of usage.
- Can I build AI voice agents on Orbit like I do on Synthflow?
- Yes. Orbit is AI-first: you build and deploy AI voice agents on a real-time streaming pipeline, the same core Synthflow is built around. The difference is that on Orbit those agents sit next to SMS, WhatsApp, email, video, and a human contact center on one platform, so a conversation can move across channels without leaving the account. Orbit also runs the LLM, speech-to-text, text-to-speech, and telephony legs of that pipeline itself, so a healthcare customer can cover the whole stack under one Business Associate Agreement with Devotel — whereas Synthflow's bring-your-own-API-key model means you connect your own providers, so your organization is responsible for separately obtaining and managing a BAA with each one.
